This patchset extracts the public SM4 algorithm as a separate library, At the same time, the acceleration implementation of SM4 in arm64 was adjusted to adapt to this SM4 library. Then introduces an accelerated implementation of the instruction set on x86. This optimization supports the four modes of SM4, ECB, CBC, CFB, and CTR. Since CBC and CFB do not support multiple block parallel encryption, the optimization effect is not obvious. And all selftests have passed already. The main algorithm implementation comes from SM4 AES-NI work by libgcrypt and Markku-Juhani O.
